# 370.39 To what extent is a digital signature admissible in any civil litigation or dispute?

In asserting a digital signature against you in any civil litigation or dispute, extrinsic evidence of authenticity as a condition precedent of admissibility (such as testimony about the scientific validity of digital signatures) is not necessary to establish:

(a) That a digital signature corresponds to a specific public key pair, and;

(b) That an electronic message to which the digital signature is affixed has not been altered from its original form.
